WATER-HEATER.

srnorFIoA'rroN forming part of Letters Patent No. 517,572, date April1894- Application filed January 18. 1892. Serial No. 418,432. (Nomodel.)

To aZZ whom it may concern.-

Be it known that I, EDWARD HAYES, of Rochester, in the county of Monroe,in the State of New York, have invented new and useful Improvements inWater-Heaters, of which the following, taken in connection with theaccompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in heating apparatus particularlyapplicable for use with the portable boilers of fire engines and likedevices, and hasfor its object the production of a simple and effectiveconstruction which is readily connected to the portable boiler forcausing a constant circulation of hot water to flow therethrough and isread-' ily detached therefrom for permitting the hasty removal of theportable boiler; and to this end it consists, essentially, in a heatingsystem, a watery circulating system, the water of which is. heated bythe former system, a pair of fixed pipes connected to theWatercirculating system and having their extremities adapted to beconnected to the inlet and outlet pipes of the portable boiler, andmovable rods in the fixed pipes for opening check valves upon the inletand outlet pipes of theportable boiler. j

The invention furthermore consists in the detail construction andarrangement of the parts, all as hereinafter more particularly describedand pointed out in the claims.

In describing this invention,reference is had to the accompanyingdrawings, forming a part of this specification, in which, like lettersindicate corresponding parts in all the views.

Figure 1 represents an elevation, partly in section, of my improvedinvention shown as supported on sections of a pair of floors and asoperatively connected to the portable boiler of a fire engine. Fig. 2 isa longitudinal vertical sectional view of my improved heating apparatus.7 Fig. 3 is an enlarged longitudinal vertical sectional View of one ofthe pipes projecting from the portable boiler and one of the fixed pipesof the water circulating system adapted to receive the end of the boilerI pipe, illustrating clearly the rod movable in upon the upper face ofsaid floor.

Fig.4 is a similar view to Fig. 3, the twopipes being separated and themovable rod withdrawn from operative position. Y

A- represents any suitable construction of fire engine adapted to benormally supported upon a floor a and having its boiler -B provided witha suitable inlet and outlet consisting preferably of projecting pipes band b provided at their ends with check valves b the pipes-bb' beingpreferably provided with removable wearing ends b v cc represent a pairof fixed pipes connected at one end to a water circulating system --Cand formed with the removable Wearing extremities c having the bellshaped outer end -c for receiving the wearing end -b of the pipes bb,when the portable boiler is backed into its normal position in proximityto the water circulating system. The endsc of the wearing extremities cof the pipes -c-c' are provided on their interior with suitable packingoFig. 3, for makinga tight joint when the ends b of the pipes bb are inposition, thus permitting the circulating water to How through theboiler from the water circulating system O c-c' are held fixed in anydesired manner as by a bracket o having one'end formed with suitableopen eyes o c for receiving the wearing extremities of the pipes and theother mounted upon the floor a, and by means of the pipes C andGpresently described, to which the fixed pipes cc' are respectivelysecured. These pipes -O -O are passed through an opening a in the floora, and are provided with a shoulder a**-, which rests Movable withineach of said pipes -c cis a rod -D- having one extremity -dextendingbeyond the pipe through a bushing dand provided with a hand piece d" andthe other extremity -d movable in a bearing d within the pipe andadapted to project beyond the outer ends o of said pipes and within thecheck valve -b* for rocking the valve piece b backwardly and opening thecheck Valve to'permit the circulation of the Water.

When the fire engine is returned from a fire The pipes" or other outdoorservice, the operator engages the hand engaging pieces d*-- and drawsthe movable rods D backward until their progecting ends are within theextremities -c so that the engine may be backed into position withoutliability of bending said rods, and, after the engine is connected withthe water circulating system by backing the same 1nto suitable proximityto the pipes -cc'-, the rods D- are then forced toward the portableboiler for opening the check valve.

In order to guide the engine in its movement upon the floor atoward thepipes -cc-- for connecting its boiler B- with the water circulatingsystem -C I preferably use guides -a consisting of ribs proectingupwardly above the floor a. I have here illustrated only one of saidguides as at the outside of one of the wheels, but it will be readilyapparent that a second guide 1s arranged at the outside of the otherwheel. In some cases the fire engine is drawn upon 1ts supporting floora-- front first instead of being backed thereupon, and, as it is thennecessary to reverse the position of the engine, the guides -a areformed very short and utilized to guide only the extreme rearwardmovement of the engine when reversed to its normal position.

"When the portable boiler is quickly withdrawn from the watercirculating system, as is required in the use of a fire engine, theoperator has no time to turn valves and similar 1 devices, and for thisreason I have provided the check valves -b-, which close automaticallyand prevent the escape of water from The water circulating system C- isheated by a heating system -F, and consists,

essentially, of a series of pipes or conduits -O' mounted within a shellC suitably supported beneath the floor --aas upon a -F, which, aspresently stated, forms a part of the heating system.

Upon reference to the drawings it will be or conduit C through the pipes-C -cinto the boiler l3-, thence from the boiler B through the pipes-c-C and into the lower head or conduitC The water within thecirculating system is thus shut off from entrance into the chamber orconduit --F and, as previously stated, the water within the pipes -cc'-is free to escape into the catch basin E.

To permit entrance of water to the water circulating system forreplenishing the waste caused by the operation of the engine in orderthat its boiler may be full when starting for a fire I provide asuitable inlet pipe -G- connected to thelower end of the return pipe -Cand provided with a valve It is frequently necessary to remove the waterfrom the heating system, and for permitting this operation I provide anoutlet pipe G- having one end connected to the lower horizontal portionof the return pipe --C, which, it will be noted, is beneath the lowerhead -C and having its other end directly above a catch basin -g'- fromwhich the water is conducted by a waste pipe g The outlet pipe -G'- isformed with a valve --g, which is closed when the water is circulatingthrough the system -C- and the boiler -13.

The heating system -F- consists, essen of the water tank and the upperextremity of the chamber -F and the pipe or conduits F between the upperextremity of the water leg -F and the lower extremity of the chamber FThe heater -F'-may be of any desirable form, size, and constructionbeing here shown as provided with a combustion box f, a fuel inlet dooran ash-box l--f", a smokepipe -f--, and as mounted upon a floor --abeneath the upper floor -aupon which the engine A-- is supported.

The shell C for supporting the pipes or conduits -G- ot' the watercirculating system and containing the chamber or conduit F of theheating system is preferably supported with its upper end abovethecorresponding end of the heater by means of a suitable bracket -l'Isecured to the heater section --F The feed tank -F is supported abovethe heater lf-- upon the floor a, and may also be of desirable form,size, and construe tion, being here shown as cylindrical and assupported upon a bracket f Upon reference to the drawings and theforegoing description of the heating system it will be evident that asclearly shown by the arrows 2 at Fig. 1 the water passes from the upperextremity of the water leg F through the pipe F into the chamber Fthrough the pipe F to the upper extremity of the feed tank F thencethrough the pipe -F into the lower extremity of the water leg F Water isadmitted to the heating system by a pipe I- discharging into the lowerend of the pipe F and formed with a valve 1I--, and is withdrawn fromsaid system by an outlet pipe I having one end opening from the base ofthe water leg F and provided with a valve i and the other discharginginto the catch basin g'.

It will be particularly noted that the water or' other fluid used in theheatingsystem is entirely shut off from the water of the-circa latingsystem so that the circulation within the heating system continuesconstantly without being affected by the presence or removal of theportable boiler B-, whereas the removal of the portable boiler -B breaksthe circulation of the water circulating system. This constructionenables the firemen or other attendantsof the heating apparatus to usethe water from the circulating system for bathing orother purposes,without permitting thewithdrawal of the water from the heating systemand thus affording a liability of the same being unduly burned throughlack of water therein.

The operation of my invention will be readily perceived from theforegoing description and upon reference to the drawings, and it will beparticularly noted that the parts are simple, strong and effective, andwell suited for the designed purpose; that the water of the circulatingsystem is entirely shut off from that of the heating system; that aconstant circulation is passed through the boiler of the engine when inposition, and that the same may be readily withdrawn without theoperation of any valves or liability of escape of water from the boilerof the fire engine.

It is evident that the detail'construction and arrangement of the partsof my heating apparatus may be somewhat varied from that shown anddescribed Without departing from the spirit of my invention, hence I donot herein limit myself to such precise detail construction andarrangement.
